Summary review of C + + class design------destructor

After you create an object with a constructor, the program keeps track of the object until it expires. After the object expires, the program calls the destructor to complete the cleanup of the object.

Several features of the destructor:

1. There can be only one destructor, and if there is no explicit definition, the compiler will automatically generate a default destructor;

2. Destructors cannot be overloaded;

When the destructor is called:

1. If you create a static storage class object, the destructor will be called automatically at the end of the program;

2. If you are creating an automatic storage class object, the destructor will be called automatically when the program executes the code block;

3 If the object is created through new, it will reside in the stack memory free of storage, when using delete is called;
